Hi there! Hopefully this helps!

$2e = 2$

Divide both sides by 2.

$e = \frac{2}{2}$

<h2>Divide 2 by 2 to get, you guessed it, 1!</h2>

In the smallest of the three triangles (with sides $a,b,3$ ) we have

$a^2+3^2=b^2$

In the second-largest triangle (with sides $a,108$ ), the length of the missing side is $\sqrt{a^2+108^2}$ . Then in the largest triangle (with sides $b,111,\sqrt{a^2+108^2}$ ), we have

$b^2+\left(\sqrt{a^2+108^2}\right)^2=(108+3)^2=111^2$

$\implies b^2+a^2+108^2=111^2$

$\implies b^2+a^2=657$

Equivalently, we have

$(a^2+9)+a^2=657\implies 2a^2=648\implies a^2=324\implies a=18$

In turn, we find

$b^2=18^2+3^2=298\implies b=\sqrt{333}=3\sqrt{37}$

Can you simplify these please thank you

-4(9-3)/(8-2) = -4

(8^2-2^5)/(24/6)+3^2= 17

5(16-5)-1/(4^2-7) = 6

Hope this helps! Please rate if I helped you! Any questions please just ask! Thanks!!
